Therefore, the cleaning fluids cannot enter into the cavity 122.

To access the electrical enclosures 160, the door 58 is opened. The electrical enclosures 160 are located at eye/waist level. A Human- Machine Interface (HMI) 162 is also mounted on the door 58.
  • HMI Human- Machine Interface
  • the components had to be bolted together which was time consuming. With the present food product forming machine, the large one-piece weldment that forms the body 28 of the food product forming machine 20 avoids this.
  • a customer can order the food product forming machine 20 in more than one size. Most of the components of the food product forming machine 20 can be used for all sizes. Different sizes of the food product forming machine 20 have different widths of the pump assembly 30, the mold plate 104, the knockout mechanism 34, the conveyor apparatus 36 and the lift assembly 146. Therefore, the food product forming machine 20 can be provided in different sizes by only changing these components which are downstream of the tunnel 72. This provides a significant cost savings for the manufacturer.
